Subject: [PATCH] kernel-install: Only read cmdline from /proc/cmdline when not
 in container

If we're running from within a container, we're very likely not going
to want to use the kernel command line from /proc/cmdline, so let's add
a check to see if we're running from a container to decide whether we'll
use the kernel command line from /proc/cmdline.
